where \(\kappa _5\)  is the five-dimensional Newton constant and \(V(\phi )\)  is a potential encoding the details of the dual gauge theory. In [1]}, the following potential has been considered
\(L^2 V=-3 -\frac{3}{2} \phi ^2 - \frac{1}{3} \phi ^4 + \left( \frac{1}{3 \phi _M^2} + \frac{1}{2 \phi _M^4}\right) \phi ^6-\frac{1}{12 \phi _M^4} \phi ^8 \, .\)
